Bier spots are asymptomatic white anemic macules with irregular shape located on the upper limbs and less often on the lower limbs and trunkus. They are observed predominantly in youg males and may be idiopathic or associated with other conditions. We report two cases with Bier spots in which videodermatoscopy and nailfold capillaroscopy were performed. Patient 1 was a 34-year-old otherwise healthy male who presented with white spots on his upper limbs for 10 years. Dermoscopy revealed marked narrowing of skin capillaries within the borders of white macules whereas capillaroscopy pattern was normal...

Trichomycosis axillaris is a common but underdiagnosed condition of the skin. The dermoscopic image of this disease is not previously described in the scientific literature. We believe that dermoscopy is a convenient and interesting diagnostic method that may aid in the diagnosis.

Dermatologists are often faced with the challenge of patients presenting with non specific symptoms such as itching and or erythema. These symptoms may be attributed to a number of diseases, many of which are trivial, and others even life-threatening. In order to establish the correct diagnosis, dermatologists must rely on good diagnostic tools and knowledge. Dermoscopy was introduced mainly for inspection of pigmented lesions, but its use has now also spread to non-melanoma skin cancer, inflammatory diseases, and almost any skin disease...

Sebaceous carcinomas are rare but potentially fatal malignant adenocarcinomas with varying degrees of sebaceous differentiation. Several dermoscopic findings of extraocular sebaceous carcinomas have been reported; however, there are no previous reports of ocular sebaceous carcinomas detected using dermoscopy. We present a case of ocular sebaceous carcinomas showing specific findings from dermoscopy, and describe the common dermoscopic characteristics. In our cases and a review of cases in the literature, we noted that polymorphous vessels and yellowish areas were observed in all eight cases...

Palmar syphiloderm is one of the most common presentations of secondary syphilis and its recognition is of utmost importance in order to promptly identify such a disease and initiate appropriate workup/management. However, the differential diagnosis with palmar papular psoriasis often poses some difficulties, with consequent possible diagnostic errors/delays and prescription of improper therapies. In this report, we underline the role of dermoscopy as a supportive tool to facilitate the non-invasive recognition of palmar syphiloderm and its distinction from palmar papular psoriasis...

Recently, intensive research on photoacoustic (PA) imaging has been conducted to accelerate the development of dermoscopy of the human skin. In this Letter, we first developed a PA dermoscope equipped with a waterless coupling and impedance matching opto-sono probe to achieve quantitative, high-resolution, and high-contrast imaging of the human skin. Compared with the commonly used liquid-coupled PA probes, the human-skin-adapted probe can facilitate implementation in the clinical setting. The noninvasive imaging experiments of epidermal and dermal structures in volunteers have been carried out to demonstrate the high imaging quality that can be obtained by using such an opto-sono probe for a PA dermoscope...

There have been few studies investigating diagnostic accuracy between plastic surgeons, or comparing this with dermatologists. Use of dermoscopy by dermatologists has widened the diagnostic gap between dermatologists and plastic surgeons, with plastic surgery lagging behind dermatology in learning this technique. Consequently, plastic surgeons are likely to have a lower threshold for performing a diagnostic or excisional biopsy than dermatologists, leading to a higher rate of intervention for lesions that could otherwise be managed non-surgically...

The treatment of pigmented lesions includes several approaches depending on the nature of the cutaneous lesion to be treated. When considering melanocytic lesions, a balance between therapeutic aspects and cosmetic concerns for aesthetic sites have to be taken into account, with particular attention for the differential diagnosis between benign and malignant.(1-3) In particular, the increasing awareness for good cosmetic results lead to the development of less invasive techniques, although they hamper the histological assessment, which is the gold standard for the diagnosis of melanocytic lesions...

BACKGROUND/OBJECTIVES: The clinical and dermoscopic differential diagnosis of flat pigmented facial lesions represents a great challenge for the clinicians. Our aim was to report a quantitative method based on dermoscopic features to better classify pigmented facial lesions. METHODS: This is a retrospective case-series study that analysed the dermoscopic features of 582 pigmented facial lesions. RESULTS: The individual patient probability of lentigo maligna (LM) was predicted by a multivariate model, with an accuracy of 0...

BACKGROUND: Desmoplastic melanoma (DM) is frequently misdiagnosed clinically and often associated with melanoma in situ (MIS). OBJECTIVE: To improve the detection of DM using dermoscopy and reflectance confocal microscopy (RCM). METHODS: A descriptive analysis of DM dermoscopy features and a case-control study within a melanoma population for RCM feature evaluation, performed blindly, using data obtained between 2005 and 2015. After retrospectively identifying all DM cases with RCM data over the study period (n=16), a control group of non-DM melanoma patients with RCM data, in a ratio of at least 3:1, was selected...

BACKGROUND: Arborizing vessels (AVs) are dermoscopically defined as telangiectasias with distinct treelike branching, and are a characteristic feature of basal cell carcinoma (BCC). However, AVs are observed in various conditions other than BCC. OBJECTIVE: The aim of this study was to investigate skin diseases showing AV and investigates dermoscopic differences between BCC and non-BCC. METHODS: Dermoscopic images showing AV were prospectively collected and classified into BCC/non-BCC...

BACKGROUND: Dermoscopy is a useful tool for earlier diagnosis and differentiating benign lesions from melanoma. OBJECTIVES: We aim to investigate dermoscopic features of acral nevi, age, and localisation-related findings of these lesions. METHODS: This was an observational, descriptive study. Patients were retrospectively collected from the Department of Dermatology. The patients with acral nevi were included in the study. Inclusion criteria were Turkish nationality and the presence of at least 1 acral nevus diagnosed both clinically and dermoscopically...

Importance: Pigmented facial macules on photodamaged skin are a clinical, dermoscopic, and histopathologic challenge. Objectives: To clinically and dermoscopically characterize, by means of reflectance confocal microscopy (RCM), ambiguous pigmented facial macules and establish a correlation between RCM, histopathologic, and immunohistochemical findings. Design, Setting, and Participants: A prospective study of ambiguous pigmented facial macules on photodamaged skin was conducted in a tertiary referral center for dermatology between January 1, 2009, and December 31, 2015...

Nail dermoscopy was initially used only in the assessment of nail pigmentation, but now it is widely utilized for the evaluation of many nail disorders. In daily practice, dermoscopy may confirm clinical diagnoses and guides in the management of nail diseases and treatments, permitting a better visualization of symptoms. Dry dermoscopy is required for evaluation of the nail plate surface, while gel as an interface is necessary for assessment of nail pigmentation and onycholysis, as well as for the evaluation of the distal nail margin...

BACKGROUND: The differential diagnosis between regressing nevi and melanoma might be challenging; regressing areas can represent a confounding factor for the diagnosis and the histology still remain mandatory to rule out melanoma. Reflectance confocal microscopy may add valuable information by revealing features suggestive of the nature of the melanocytic proliferation. OBJECTIVE: To assess the impact of confocal microscopy in the management of regressive melanocytic lesions...

Trichomycosis is a superficial infection caused by Corynebacterium flavescens, which regularly affects axillary, and to a a lesser extent, pubic, scrotal and intergluteal, and exceptionally, head hairs or trichomycosis capitis (TC). This condition is characterised by the formation of bacterial nodules. Clinically, it can be confused with white piedra or pediculosis. The diagnosis is made by microscopic and dermoscopic observation and confirmed by culture. OBJECTIVE: To present a case of TC in an infant and illustrate the microscopic, dermoscopic, and ultrastructural characteristics...
